How Axle Counting Works
The Port Authority charges by total axle count on the road. The toll gantry has overhead axle-detection sensors that count every axle passing underneath, from the front axle of the lead vehicle to the rear axle of the trailer. The E-ZPass transponder identifies the class of the lead vehicle, and the axle count determines the rate tier.
A 2-axle car (passenger class) towing a 1-axle utility trailer triggers 3 axles total. The system charges the 3-axle truck rate of $68.01 E-ZPass peak. The same 2-axle car towing a 2-axle trailer (the more common configuration) hits the 4-axle rate of $90.68.
Trailer Axle Tier by Tier
+1 axle (single-axle trailer) moves you from car ($16.79) to 3-axle ($68.01) — a $51.22 jump. This is the largest single jump in the schedule because the car-to-truck classification transition happens at this level.
+2 axles (dual-axle trailer) moves you from car to 4-axle ($90.68) — adds $73.89 over the bare car rate.
+3 axles (triple-axle gooseneck) moves you from car to 5-axle ($113.35) — adds $96.56.
Truck Plus Trailer (Heavy Combinations)
A 3-axle truck (e.g. heavy-duty pickup with rear tandem) plus a dual-axle trailer = 5 total axles, $113.35 E-ZPass peak. A 3-axle truck plus a triple-axle trailer = 6 axles, $136.02. Tractor-trailer 5-axle combinations (3-axle tractor + 2-axle trailer) hit the standard 5-axle commercial rate of $113.35. See full commercial schedule.
Upper Level Required
Any vehicle towing a trailer must use the upper level. The lower level prohibits trailers regardless of total height. This is enforced at the New Jersey approach via signage and ultimately by the physical 13ft 6in clearance bar on the lower-level entrance. The toll is identical on both levels, so the upper-level routing does not cost extra.
Saving on With-Trailer Crossings
Off-peak hours save $3.00 to $6.00 per crossing depending on axle count (the per-tier off-peak discount grows with axle count). A car + dual-axle trailer saves $4.00 off-peak ($86.68 vs $90.68). A 5-axle truck-trailer combo saves $5.00 off-peak ($108.35 vs $113.35).
E-ZPass saves $12.00 to $20.00 per crossing vs Toll-by-Mail for trailer combinations. For frequent trailer towing (e.g. weekly equipment hauling), the annual savings easily exceed $1,000.

Frequently Asked Questions
How does the GWB toll change if I am towing a trailer?
The Port Authority counts total axles on the road, including the trailer. A 2-axle car towing a 1-axle utility trailer = 3 axles total, tolled at $68.01 E-ZPass peak (the 3-axle truck rate). A 2-axle car towing a 2-axle trailer = 4 axles, tolled at $90.68. Each additional axle moves you up one rate tier. Tariff effective 4 January 2026.
Is a single-axle trailer cheaper to tow across the GWB?
Yes. A single-axle trailer adds 1 axle (3 total with a 2-axle car), tolled at $68.01 E-ZPass peak. A dual-axle trailer adds 2 axles (4 total), tolled at $90.68. The difference is $22.67 per crossing. For frequent towing, choosing a single-axle trailer when load capacity allows saves significantly.
Can I take a car-and-trailer combination on the GWB lower level?
No. Vehicles towing trailers must use the upper level regardless of total height. The lower level prohibits trailers. The toll is the same on both levels, so there is no cost penalty, but the routing is mandatory.
Does my E-ZPass handle the trailer axles automatically?
Yes. The toll gantry has overhead axle-detection sensors that count every axle on the road as you cross. Your E-ZPass identifies the class of the lead vehicle, and the system adds the trailer axles automatically. You do not need to declare the trailer in advance or change account settings.
Are boat trailers and horse trailers tolled the same?
Yes. The Port Authority does not distinguish trailer types. A boat trailer, horse trailer, car-hauler, utility trailer, gooseneck, and fifth-wheel are all counted by axle. A single-axle trailer of any type adds 1 axle. A dual-axle trailer adds 2 axles. The cargo or type does not matter, only the axle count.
